A stockroom worker pushes a box with mass 13.5 kg on a horizontal surface with a constant speed of 3.00 m/s . The coefficients of kinetic and static friction between the box and the surface are 0.280 and 0.440, respectively.What horizontal force must the worker apply to maintain the motion of the box? (Express your answer in newtons. Assume that +x direction coincides with the direction of velocity.)If the worker stops pushing, what will be the acceleration of the box? (Express your answer in meters per second squared. Assume that +x direction coincides with the direction of velocity.)

A stockroom worker pushes a box with mass 13.5 kg on a horizontal surface with a constant speed of 3.00 m/s . The coefficients of kinetic and static friction between the box and the surface are 0.280 and 0.440, respectively.

What horizontal force must the worker apply to maintain the motion of the box? (Express your answer in newtons. Assume that +x direction coincides with the direction of velocity.)
If the worker stops pushing, what will be the acceleration of the box? (Express your answer in meters per second squared. Assume that +x direction coincides with the direction of velocity.)
